Matchstick Puzzle - Fix The Equation  

There are 15 Matchstick Puzzles (fix the equation) presented in this video, Give it a try before checking the solution. Comment if you found an alternate solution.

Puzzle 1. Move the same matchstick to form the second number to a 6. 3+6 = 9

12th could be 0 + 0 = 0

On Puzzle 6 I had a different way. I moved the vertical matchstick from the addition sign and moved it horizontally at the top of number 1. Which is 7 - 2 = 5 instead of 1 + 2 = 3. I also found an alternative answer on Puzzle 11. Instead of 4 + 5 = 7, my alternative answer is -4 + 5 = 1. I’ve done it by moving the horizontal matchstick from the top of 7 and moved it next to the 4 in the beginning of the equation. By the way, this is a good logic test to get my brain going. Looking forward to more logic videos like this.

Puzzle 2. Move the upright stick from the plus sign to make a 9 out of the first number. 9-6=3

#6 has alternative solution: move vertical match from "+" to "1" to make "7"

@4:36 can also be solved to 7 - 2 = 5 by moving vertical stick of plus sign toadd to first stick making the 1 a 7 .....double solution!

6th one could be 7 - 2 = 5

The 0+0=6 can also be changed to 0+0=0

Question 14 answer 2, move the top line on the seven to the top of the one and then it’s 6+1=7

#14 the vertical stick on the "+" can be moved to the other side of the "=" to make "-1", giving: 6-7=-1

Problem 2 alternate: take the vertical match in the plus sign to make the 4 a 9. 9-6=3. Update: see comment by @AzureKyle below. Problem 6 alternate: take the vertical match in the plus sign to make the 1 a 7. 7-2=5. Problem 12 alternate: take the middle horizontal in the 6 to make that 6 a 0. 0+0=0.

#14 : from 6+ 7 = 1 ---> 6 +1=7

Very nice logic test to get my brain going at the start of the day, thank you. Rearranging some of the answers, though, breaks the rule of moving only 1 stick. 🙂

Alternative solutions #6: use the vertical stick of the plus to turn the 1 into a 7; 7 - 2 = 5 #14: The same as in #5 and #9, use the horizontal stick of the 7 to turn the 1 to a 7; 6 + 1 = 7

1:44 or you could grab a match from the top cross in the addition symbol to make the 4 a 9 so 9 - 6 = 3

#13. I was going to suggest grab the match on top of the 7, break it in two and put the small pieces over and under the - (minus) symbol to turn it into ÷ (division). So 4/4=1 😹

I found it easier to think about the possible options mathematically first, then it was easy to spot how you could get numbers you need.

Note, these are guesses while the video is paused between each problem. Problem 1: Swap the top left of the 9 to make it 3, put it on the bottom left of the 5 to make it 6. 3+6=9 Problem 2: Swap Bottom left of 6 to make it 5, put it on top left of 3 to make it 9. 4+5=9 Problem 3: Swap the vertical line of the plus sign, making it a minus sign, and put it on the 1 to make it 7. 7-5=2 Problem 4: Rotate the middle line of the 4 clockwise to turn it into 11. 11-5=6 Problem 5: Swap the top line of the 7 to make it a 1 and move it on the bottom left of the 5 to make it a 6. 6+1=7 Problem 6: Same as problem 3. 7-2=5 Problem 7: Swap the top right line of 8 to make it a 6 and put it on the bottom left of the 9 to make it an 8. 8-6=2 Problem 8: Two possible solutions for similar answers. Either rotate the middle line of the 6 clockwise to make it a 0 (8+0=8) or Swap the middle line of 8 to make it a 0 and put it in the top right of the 6 to make it an 8. 0+8=8 Problem 9: Swap the top line of 7 to make it a 1 and put it on top of the 1 to make it a 7. 1+6=7 Problem 10: Same as problem 7. 2+6=8 Problem 11: Swap the top left line of the 5 and put it on the top right to make it a 3. 4+3=7 Problem 12: Spotting three solutions for this one, with two of them being almost identical. For the identical ones, take a 0 and rotate the top right line counter-clockwise to make it a 6. Depending on the 0 you pick, it's either 6+0=6 or 0+6=6. Or, you can rotate the middle line of the 6 clockwise to make it a 0 for 0+0=0 Problem 13: Same as problem 4. 11-4=7 Problem 14: Same is problem 9. 6+1=7 Problem 15: Swap the top right stick on the 9 and put it on the bottom left to make it a 6. 7-1=6

#13 - take the horizontal bar from the 7. Break it in half and put the halves above and below the - sign to make it a division sign #14 - 6-7 = -1

Puzzle 11 could have been changed into -4 + 5 = 1 and would be correct. I'm sure there is more than one way to solve most of them without using the illegal symbols stated at the start of the video.

11 - 4 = 7 .... move 1 horizontal stick on first 4 and make number 11...

In problem no. 6 There is 1+2=5 There we can remove one stick from the '+' sign and join horizontally with the no. 1. So, we get here 7 - 2 = 5

Move the "cross bar" of the first 4, by rotating it DOWN a quarter turn (90º) to turn the 4 into an 11 : 11 - 4 = 7.

9:39 Is breaking a stick allowed? If so, then I solved puzzle 13 with 4/4=1, by breaking the top stick of 7 and making a traditional dot-above-and-below-a-minus-sign divided by symbol, like a % straightened out. I noticed that when solving the thumbnail before I clicked.

I like the tune

The only easiest solution here is take the equation and make it an *inequation* Like 4-4=7, move the horizontal line in the 7, rotate it 45° counter clockwise and place it in the equal sign. Now you get 4-4≠1

In the one from the thumbnail (4+4=7), I personally prefer the solution of taking the stick from the top of the 7, break the mf'er in half and use each half to make a dot above and below the minus sign.

Problem #2 take the vertical plus sign and make it a - then put it on top of the 4 making it a 9 then you have 9-6=3

4 - 4 = 7: put the minus on the equal sign. 44 ≠ 7

Everybody is here for the alternate answers. The only one that tricked me was the 4 turning into 11. I was expecting negative answers by moving half the plus sign. Haha, no inequalities. They could mostly be solved that way. 😂 I paused a lot though. Some took several minutes. Some I solved multiple ways instantly. I am calling myself below average on this. I only gave up on the 4 to 11 one.

On puzzle 12 you can turn the 6 into a 0

12 can be also soved as the 6 is converted to 0 the same way the 0 is converted to 6

2nd one could be 9-6=3 if rotations are allowed

These are kind of fun and interesting. Thanks for this!

Muy interesante gracias por la información y la agilidad mental.

14 правильных решений. Спасибо🎉😊

#1 and #6 have two solutions. Near the end, you get a feel for the patterns and it gets easier.

At #14: You could move a stick from the 7 to the left over to the 1 on the right and get the equation 6 + 1 = 7.

(1) 3+6=9

In the second puzzle, you also can take a match from the + and place it on the 4, so it becomes a 9, and then, you have 9-6= 3

question no.2 4+6 = 3 answer move the upright stick from the + and place ontop of the 4 making it a 9 = 9 - 6 = 3

4:32 7-2=5

1st one 3+6=9

Wow it's amazing.... It's good for learning with kids.

There’s an alternate answer on puzzle 9 You can turn the plus sign into a minus sign and then just put that stick to the side

They were much easier than i thought. Fun though.

8:59 another answer could be 0+0=0.

Oh tooo hard that I can't do all of the answers But I love studying math you are the best channel

Alt solution for #12 From 0+0=6 make 0+0=0

#6 could also be 7-2=5

Puzzle 4 alternative solution: Move the leftmost stick of the 4 infront of the 6: -1-5=-6

Damm getting the 4 into a 11 took me ages ... just was not thinking 2 digits I guess 🥴

Alternative to #2. Take the up match from the plus sign and put it on top of the four. 9-6=3. Puzzle 12 easy alternative answer is move the horizontal stick on six to make it a zero as well. Didn't look at any previous answers prior to submitting the above.

Puzzle 6: move the horizontal match from the + to the 1 to make 7-2=5 Puzzle 8: move the middle match from the first 8 to the 6 to make 0+8=8 Puzzle 12: rotate the middle match in the second 6 onto the empty spot on the same number creating 0+0=0 Puzzle 14: move the top match on the 7 to the 1 creating 6+1=7

#12 Alternative answer: Turn the six on the right into a zero. i.e.--0+0=0

0+0=6...instead of changing a zero to a 6 (0+6=6) I changed the 6 to a zero...0+0=0. They rest came up with your solution. 😊

Simple, I’d take the matchstick between the fours and place it diagonally “/“ over the two “equals” matchsticks.

Puzzle number two, move the match from the plus sign to make it a minus sign, and put it on top of the four to make it a nine . 9 - 6 = 3

Alternative solution for the 8th: take the central stick of the first 8 and put it in the 6, it will be 0+8=8

Moving one match to convert the 'equal' sign to a 'not equal' sign makes everything piss easy and still mathematically correct.

For 6 I have a different solution. Move the stick from the plus sign (making it a minus) and add it to the 1 , giving you 7-2=5

Puzzle 2, move one from the + sign to the 4 to make it 9-6=3.

different solution - second one - make it 9 - 5 =3 moving vertical plus to the top of the 4

So far I've noticed that some of these equations have double solutions. Without breaking the rules, are there any triples?

#12 I moved the middle stick on the answer 6 to make the equation 0+0=0 😂 What I saw first, and still was a correct answer! LOL

7-2=5

3+5=8

Some of the puzzles have more than one solution.

Haven’t seen the video. But you solve the thumbnail by making it 11-4=7.

Got one right. About to give up around #6

amazing, greetings from Bolivia

#9 : 7-6 = 1 removing the vertical bar from the + but not putting it elsewhere is valid ? #14 : 6 - 7 = -1 ?

Question 6 alternative answer. Change the plus into minus by taking the upper matchstick. Place it on the first digit to make 7: 7-2 = 5

Бессмысленные головоломки! Если ты не знаешь чего хочешь, разве можно что то сделать? 😊

8:30 #12 alternate solution: 0 + 0 = 6 We also can move the central stick from 6 to make a 0. Then 0 + 0 = 0 😊

Puzzle 12 change the top right second 0 to make a 6 0+6=6

Puzzle number 14. Take vertical stick from + and put it in front of 1. It makes 6-7=-1

1+2=5 could also have been 7-2=5

#14 6-7 = -1

Ha good one on the thumbnail. Took me a minute to figure it out what to do with 4 - 4 ! Very devious!! I approve...

There is another solution to the 14th problem. You can take the top match off the 7, and that will turn it into a 1. You put that top match on top of the 1, and that will turn it into a 7. That would turn that problem into 6+1= 7.

i did the no. 2 differently. from 4+6=3 ....to.... 9-6=3. (u move the vertical stick from + and put it on top of 4, then u'll get 9)

For puzzle #6, move the vertical match from the plus sign to the first number to make it a 7. So, 7 - 2 = 5

4:12 You can move the vertical stick of the plus symbol and turn it horizontal and put it on top of the 1 to make it 7-2=5 and thats right as well

lolo didnt get the 1st one the 2nd one can be also be done with 9-6=3, and #6 can be done also with 7-2=5 but then am i allowed to change signs.. i got caught out with the 11-5 lol that was sly of you good fun thanks.

Puzzle 14 remove the top of 7 and put it on 1 to make 6+1=7

#14: 6+7=1 Your answer ( 8 - 7 = 1 ). It can made in this way, moved the top stick from 7 to the 1 , ( 6 + 1 = 7 ) which was still kept in the way of addition.

-4+5=1

8-6=2

11-4 = 7 The 1st one that I've solved 🎉🎉🎉

I was more fixated on the music than the equations. That song "Read All Over" by Nathan Moore reminds me of Nelly Furtado's "Why Do All Good Things Come To An End?"

solved the thumbnail it .5 seconds. Move the middle stick of the first "4" to make "11".

8:54 "0+0=6 goes to 0+0=0" True

Very,very good.

0+8=8

I liked most of these but turning a 4 into 11 doesn’t make sense using the 7 segment numbers.

I got almost all of them, but I had to pause the vid to give me more time to figure it out, so I guess I didn’t do so well….

Q.2 put the straight line from the plus on top of the four to make it a nine

There are 2 ways to do the 2nd puzzle. Move 1 match stick off the + sign and put it at the top of the 4 to make 9-6=3
